What is "-d $internet" ?
If $internet is 0.0.0.0 (as it should be) then you don't need to specify it
as this is assumed.

Did you try SNAT :
iptables -t nat -A POSTROUTING -o <if_inet> \
  -s 192.168.250.0/24 -j SNAT --to-source <ip_inet>

Do you have a FORWARD rule in place that allows MASQ/SNAT, or do you have
FORWARD policy set to ACCEPT (which you should not do) ?

Do you have "echo 1 > /proc/sys/net/ipv4/ip_forward" ?
